1. States Of Matter
K 2.1 Solids

2. Solids Matter-anything that takes up space and has mass.
States of matter-matter is either in a solid, liquid, gas phase
Atom-smallest particle that makes up matter.
Kinetic Theory of Matter-Brownian motion

4. Solids All particles in objects are in constant, random motion.
Kinetic – motion
Temperature affects the level of molecular motion.
No molecular motion at absolute zero.
Absolute zero is at 0OKelvin or OC

6. Solids At higher temperatures, atoms collide more often.
Crystalline solids-repeating geometric patterns.
Non-crystalline-amorphous. Non-repeating patterns.

8. Liquids Liquids have surface tension.
Liquids have no definite shape but a definite volume.
Surface-tension is caused by cohesive forces between molecules.
Viscosity-resistance to flow

11. Gases
Gas – matter that doesn’t have a definite shape or a definite volume.
Gas would fill a container completely.
Vapor – matter that is in a gas state but generally a liquid or solid at room temperature
